The unexpected decision by the Republican-controlled body is a blow to the president’s high-profile mission to revive the struggling US coal industry

An independent energy agency on Monday rejected a Trump administration plan to bolster coal-fired and nuclear power plants with subsidies, dealing a blow to the president’s high-profile mission to revive the struggling coal industry.

The decision by the Republican-controlled Federal Energy Regulatory Commission (FERC) was unexpected and comes amid repeated promises by Trump to rejuvenate coal as the nation’s top power source. The industry has been besieged by multiple bankruptcies and a steady loss of market share as natural gas and renewable energy have flourished.
